StorONE
StorONE is a New York-based enterprise storage software company founded in 2011 by Gal Naor and Raz Gordon. Its ONE Storage Platform separates storage services from hardware, delivering block, file and object storage from a single, hardware-agnostic engine. By rewriting the storage stack from scratch, StorONE combines high performance, real-time auto-tiering across flash and HDD, immutable-snapshot ransomware recovery and per-drive licensing to help enterprises cut storage costs while running on commodity servers.
Quobyte
Quobyte is a software company that turns commodity x86 or ARM servers into a unified, high-performance, software-defined storage system spanning file, block, and object interfaces. Founded in 2013 by two ex-Google engineers who previously built the open-source XtreemFS parallel file system, Quobyte applies hyperscaler design principles - resilient software rather than exotic hardware - to enterprise, HPC, and AI storage. Its Data Center File System combines NVMe and HDD tiers in one architecture and is used by organizations including Siemens Healthineers, robotaxi maker Zoox, the UK's STFC/JASMIN supercomputer, and Yahoo Japan.
